Webb2 apr. 2024 · A Type I error occurs when a true null hypothesis is rejected. A Type II error occurs when a false null hypothesis is not rejected. The probabilities of these errors are denoted by the Greek letters α and β, for a Type I and a Type II error respectively. WebbA Type I error is when we reject a true null hypothesis. Lower values of \alpha α make it harder to reject the null hypothesis, so choosing lower values for \alpha α can reduce the probability of a Type I error. The consequence here is that if the null hypothesis is false, it may be more difficult to reject using a low value for \alpha α.
